corymbia maculata/hydrocarbon

The volatile constituents in leaves of Eucalyptus citriodora, including oil fraction and water-soluble fraction, were extracted and determined. Oil fraction of volatile components was obtained through steam distillation. Ether was used as the solvent to extract the water-soluble fraction of volatile

Methyl polysiloxane solid-phase microextraction fibres were used for ten minutes to adsorb volatile constituents from headspace above all or part of a single cut up fresh eucalyptus leaf kept warm at 37 degrees C. The fibres were desorbed at 200 degrees C for programmed gas chromatography (40-187
